===================================================================
ChangeSet@1.1783, 2004-06-27 15:56:35-05:00, dtor_core@ameritech.net Input: allow marking some drivers (that don't do HW autodetection) as manual bind only. Such drivers will only be bound to a serio port if user requests it by echoing driver name into port's sysfs driver attribute. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
